# TikZ is missing from the diagram type picker and there is no way to turn it on

**What you are seeing**

TikZ is missing from the diagram type picker and there is no way to turn it on.

---

## Why it happens

TikZ is off by default in the picker's default list, and the Jira edition has no settings surface that could override that list.

---

## What to do

Use another language for new diagrams. Existing TikZ diagrams still render. Only creating new ones is blocked. There is no workaround in Jira.

## A few things that catch people out

* The licence banner's own links are broken in Jira (a Confluence admin path, and a Marketplace URL missing its listing id).
